DANVERS — Lawyers for Philip Chism, the Danvers teen charged in the rape and murder of his teacher Colleen Ritzer last October, are expressing skepticism about what they've been told about the discovery of Ritzer's body.

During a hearing Thursday afternoon in Salem Superior Court, defense lawyer Denise Regan filed a series of motions seeking additional evidence, including copies of text messages and emails that she believes officers used to communicate with each other, as well as information about the time photos of Ritzer's body were taken.
